PVC conduit yog ib qho feem ntau siv cov yeeb nkab yas hauv cov hluav taws xob hluav taws xob, nrog cov yam ntxwv tseem ceeb hauv ntau yam:
Khoom Siv Lub Teeb:Ua haujlwm ntawm polyvinyl chloride, nws muaj qhov qis dua qis dua li ntawm cov kav hlau, nrog lub cev hnyav xwb 1/5 txog 1/5 txog 1/3 ntawm qhov ntawd ntawm cov khoom lag luam hlau ntawm tib qho kev tshwj xeeb. Nws yog kev ua haujlwm {{5 5}} txuag thiab yooj yim thaum lub sij hawm thauj mus los thiab tuav. Tsis muaj cov cuab yeej hnyav xav tau thaum lub sijhawm teeb tsa, thiab nws tuaj yeem ua haujlwm los ntawm ib tus neeg, tshwj xeeb yog tsim nyog rau high- qhov chaw nyob hauv nqaim.
Corrosion Kuj:Nws muaj cov tshuaj ruaj khov, tsis yog ib qho kev xeb lossis xeb, thiab tuaj yeem tiv thaiv cov kev cuam tshuam ntawm cov av noo, kua qaub} lub hauv paus, ntsev txau thiab lwm qhov chaw ib puag ncig. Thaum siv cov chaw ntub dej xws li chav dej, chav ua noj, lub sijhawm ua haujlwm ntev dua li qhov kev kho mob hlau ib txwm muaj ntev dua li ntawm cov kav dej khib nyiab, thiab tsis muaj kev kho mob hlau ntxiv ntev dua li ntawm cov kav dej khib nyiab, thiab tsis muaj kev kho mob hlau ntxiv ntev dua li {2} Teb kev kho mob hlau ib txwm muaj.
Cov rwb thaiv tsev zoo heev:Raws li qhov tsis - nws cov khoom siv hlau, txo qhov kev pheej hmoo ntawm cov hluav taws xob sab nraud, thiab yog qhov tsim nyog tshwj xeeb rau kev tso cov kab muaj zog tam sim no. Nyob rau tib lub sijhawm, nws tiv thaiv cov electrochemical corrosion teeb meem uas yuav tshwm sim nrog cov kav hlau.
Nyiaj txiag tus nqi:Tus nqi ntawm raw cov ntaub ntawv yog tsawg, cov txheej txheem ntau lawm yog yooj yim, thiab tag nrho tus nqi yog qis dua uas ntawm cov hlau hlau thiab hlau hlau. Ib qho ntxiv, kev teeb tsa ua haujlwm siab yog siab, uas tuaj yeem txuag cov nqi zog ua haujlwm, ua kom haum rau kev tiv thaiv cable {1} ntsuas cov phiaj xwm kev tsim kho.
Kev siv zog siv tau:Nws yog tus mos mos nyob rau hauv kev ntxhib los mos thiab khoov raws li xav tau (qee tus qauv txhawb nqa khaub ncaws txias), adapting rau cov kab txuas nrog complex. Nws tuaj yeem ua tiav kev sib sau sib txuas nrog cov pob qij txha tshwj xeeb los ntawm cov txheej txheem kev tsim kho tshwj xeeb, nrog cov txheej txheem kev tsim kho yooj yim, thiab tseem yooj yim kom disassemble thiab hloov thaum tom qab txij nkawm.
Cov haujlwm ntxiv:Qee cov qauv tau ntxiv nrog nplaim taws retardants, muaj qee cov nplaim hluav taws xob rov qab. Lawv tsis yooj yim los hlawv thaum raug hluav taws thiab ua rau cov pa luam yeeb tsawg dua, cov kev tiv thaiv hluav taws kub. Qhov saum npoo yog tus, uas tuaj yeem txo cov txheej cable txheej thaum xov, tiv thaiv kev nyab xeeb ntawm cov kab sab hauv.
Cov yam ntxwv no ua rau nws dav siv nyob rau hauv muaj zog thiab qaug zog tam sim no los ntawm cov chaw nyob, thiab khoom lag luam, thiab cov khoom lag luam ua kom tau txais kev tiv thaiv Cable cawv zoo.
